Of course I don't know but I'm sure no one of my coins is from an outright hack.

If you don't know your coins' history, you don't know that either.

But I know where it's from and I can rule it out by doing so.
Of course, criminals abusing any services is a different issue.
Criminals should be well aware that Bitcoin is public and not suited for their BS.

Of course, intention does matter.

In my opinion, it doesn't. I don't care if your friend has ethical concerns with the coins they receive, or if they want to sabotage Bitcoin. The result is the same. In either case, they treat the currency as non-fungible, which ultimately does the same harm.

Well, that's a great example, sabotaging Bitcoin would be a very illegimate purpose. At least I wouldn't be the one supporting it. And I believe, it should be up to the individual to make such a decision.
And, important point:
This famous fungibility only means: coins can be sent by ourselves, it's a technical thing.
It doesn't mean that everyone is forced to accept them and not allowed to do research.

If a legitimate buyer wants to purchase Bitcoin legitimately, what he'll receive anyways, of course he is entitled to request this sort of information.

Lol. Since when do we request this sort of information? It's the first time I've ever heard this as a need. Not caring about the history of my coins has worked fine so far.

Maybe it's a bit different because I believe it's a very legitimate concern for a face to face trade. There, 2 people meet anonymously in public, they don't know each other. It's sometimes very shady business.
It really depends on each case and should be rated case to case.

When you go to the groceries and pay with cash and get the change, do you ask the seller where they got the change from?

No, I don't ask because (most) supermarkets are pretty legitimate. And most money is scanned regularly to avoid fake cash.
This cash and Bitcoin comparison doesn't make any sense because cash can't be linked but Bitcoin transaction can because it is digital and public. Bitcoin is a public ledger.
This is a fundamental difference.

When you buy jewelery, do you also care about the origins of what you buy, or only about the materials that are used and the jewel itself?

Quote from: apogio on Today at 06:10:34 PM

I guess the latter. In bitcoin, the "material" is protected by bitcoin itself, assuming there are enough confirmations in the network. So, why bother about the former?

Because Blockchain is public. Cash / jewellery etc is not. And I like it how it is.
If someone doesn't like that fact, that the Bitcoin Blockchain is public, they can use Monero...

However, many thanks for your input @everyone even after this post went off-topic. Initially I just wanted to collect sites like oxt.me because we have so many Blockexplorers.
My intention was not to dive into pro / con arguments, or best practices for face to face P2P / purchases.
I'll lock this topic, many thanks for the input everyone.

Have a nice day.
